Bob Cringely has an interesting idea: That Wal-Mart could become a WiMax operator. This makes sense – and leads me to wonder who the aggregator could be in Europe. Someone with continental presence, a strong network, many locations and the coffers necessary to outcompete the regular telcos. Some of the oil companies, possibly, using gas stations? There is no Wal-Mart in Europe, the retailers are market segmented, though some chain collaboration might work. McDonalds? Lack the network and the regulatory moxie. Hmmmm…..
